Answer:
\(p = \frac{q-5r}{2}\)
Step-by-step explanation:
\(2p + 5r = q\)
We need to solve the equation for p
Our aim is to get p alone
\(2p + 5r = q\)
Subtract 5r on both sides
\(2p + 5r-5r = q-5r\)
\(2p= q-5r\)
Now divide both sides by 2 to get 'p' alone
\(\frac{2p}{2} = \frac{q-5r}{2}\)
\(p = \frac{q-5r}{2}\)
